China Fe-Si Powder core

China Fe-Si Powder core having a distributed air gap, has a lower loss at high frequencies, a magnetic core composed by 85% of iron, 9% of silicon, and 6% aluminum alloy powder.
Applications:
It is very suitable for use in the energy storage filter inductor in the switching power supply. 10,500 gauss saturation sendust core to provide a higher energy storage compared with the same size and the gap of the magnetic permeability of the ferrite or iron core, capacity.
Compared with iron powder core, Sendust better performance at high temperatures, some applications, the use Sendust than iron powder core size smaller.
Noise filter inductor must be large AC voltage without generating saturated very the suitable Sendust core. Adoption the sendust of core the size of the line filter can be reduced, because the required number of turns than the use of ferrite the body. sendust also has the magnetostriction coefficient close to zero, that is, in the audible frequency range in a very quiet noise or line current rough for.
The high flux density and low core loss characteristics and the sendust core is very suitable for power factor correction circuit, and one-way drive applications such as flyback transformers, pulse transformers.
